Setting the Input Frame Type

Use the ED-SYNC command to provision the type of framing present on the input signal.

ED-SYNC:[<tid>]:<aid>:[<ctag>]::<keyword>=<value>;

If you provision the TimeProvider to the Subtending mode (see Setting the System Mode, on page 105), then the input frame type is automatically set to Composite Clock type signals. You can set the FRMTYPE to CC, JCC, or JCC4 when the TimeProvider is in the Subtending mode.

When using E1 signals in the SSU mode, you can enter either CAS or CCS in the FRMTYPE keyword. The TimeProvider accepts both CCS and CAS inputs without a fault (if the input is fault-free).

This command has a default access level of ADMIN.
